Editor's note: Roughly 900 people have now been arrested, according to police, after a weekend of mayhem on the streets of Toronto during the G20 Summit. This is now the largest-ever mass arrest in Canadian history. No word on how many charges have been laid. Compare it to this: 497 people were arrested during the ‘October Crisis and the war measures act' in 1970, which came before Canada had a Charter of Rights and Freedoms.
